I'm trying to find a article or blog post that I can link to that clearly explains why artificial ingredients are avoided on a Paleo diet. I have searched MDA, Whole9, Robb Woff but I'm coming up empty. Can anyone point me in the right direction?
The author of this book is not exactly paleo, she is more Weston A Price than paleo, but her book probably has most of the info you are looking for. Her book is called Death By Supermarket.
This video also has some good info: http://www.youtube.com/watch?v=HC20OoIgG_Y
